Application
Propyl gallate (also known as propyl 3, 4, 5-trihydroxybenoate) is a kind of ester formed through the condensation of gallic acid and propanol. It appears as a fine white to creamy-white crystalline powder. It has long been used as a kind of antioxidants to be supplied to foods especially animal fats and vegetable oil, being especially effective with polyunsaturated fats. Propyl gallate, as an anti-oxidant, can protect the food and oils from the attack of hydrogen peroxidee and oxygen free radicals, having an effect similar to the superoxide dismutase. It can also be applied to ethers, emulsion, waxes, and transformer oil as the antioxidants.
Propyl gallate is a synthetic oil-soluble antioxidant. Propyl gallate is widely used in the food industry, pharmaceutical preparations, is an excellent oil antioxidant, used in cosmetics and as an inhibitor against ultraviolet radiation.
Function
1.Industry: Used as a stabilizer and rubber antioxidants in the manufacture of green fibers.
2.Food: Propyl gallate acts as an antioxidant in fats, fried foods, dried fish products, biscuits, quick-cooked noodles, quick-cooked rice, canned food and other foods.
3.Medicine: as an antioxidant in a variety of pharmaceutical preparations and drugs.
